I have tried to find a place where the cover art on the RD magazines is displayed. My library has the 1960’s edition on microfilm-unfortunately, only in B&W.
Does anyone know of a site where I could find these?
You could try calling or emailing them. Or even just sending them a messages on their Facebook page, that would be a bit less personal and might get a better response since ‘everyone’ can see it.
There are a few magazine covers here, but not even close to all. They seem to have a lot of the condensed books.
Probably several at eBay (also check completed listings).
